Tesla's driverless Cybercab is now running on Austin streets, but the launch is shadowed by regulators asking pointed questions about readiness and safety protocols. The company has also opened fleet sales to outside buyers—pointedly excluding its own Full Self-Driving customers—even as betting markets wager on a future SpaceX tie-up. All the while, critics note Tesla is still playing catch-up to Waymo in a robotaxi market that has yet to prove it can turn a profit.
